The upgrades came at the request of Speedway officials who were looking for more lighting effects for the new Caution Lighting System. This Crossroads LED system was designed to instantly alert the fans down the entire length of the catch fence (2/3 of a mile long) when a caution flag is thrown,” said Dana Stefanoff, President of Crossroads LED. “The software upgrades are a direct result of their request and will add numerous chasing and flashing effects to the existing installation.”
